DISK PLOW.

Application filed December 10, 1925. Serial No. 74,495.

This invention relates to disk plows, and

has for one of its objects to improve the construction and increase the eiiiciency and utility of devices of this character.

Another object of the invention is to provide a device of this character having improved means for adjusting and controlling.

the angularity of the disk elements relative to the supportingframe. I

With these and other objects in View, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim. and in the drawings illustrative of the preferred embodiment of the invention.

Fig: 1 is a plan view, and- Fig. 2 is a side elevation, of the improved apparatus.

Figs. 3 and 4 are enlarged details illus- I trating the construction of the adjustable disk supports.

The improved apparatus includes a supporting frame formed of spaced side rails member 12, and intermediate transverse members 13 and 14. The frame member 13- is extended at one end beyond the rail memher 10 while the frame member 14 is 6X tended at the opposite end beyond the rail member 11.

Connected to the outer end of the extended portion of the frame member 13 is a bracket device 17 forming a vertical bearing for a standard 18, while a like bracket 19 forms a vertical bearing for a standard 20.

At its lower end the standard'18 is offset laterally to form a journal 21 for a combined supporting andribbed guide wheel 22, while the standard 20 is likewise offset laterally to form a journal 22 for a'combined sup portingand ribbed guide wheel 23, thejournal 22being inclined outwardly and down wa' dly to support the wheel 23 at an angle to run in the bottom of the furrow formed by the disk cutters. I

Mounted on the standard 18 near its upper end are spaced stop collars 24 adjustably coupled to the standard 18 by set screws 25, while like stop collars 26 are mounted on the standard 20 and adjustably coupled thereto by set screws 27.

An adjusting collar 28 loosely engages the standard 18 between the stop collars24, while a similar adjusting collar 29 loosely engages the standard. 20 between the ste sellers 26.

A lever 30 is pivoted at 31 to the bracket 11, while a like lever 32 is pivoted at33 to the bracket 19.

The lever 30 is coupled by a link device 34 to the collar 28.

The bracket 17 is provided with a toothed segment 36 with which a pawl device 37 carried by the lever 30 cooperates, while a like toothed segment 38 is formed on the bracket 19 with which a pawl device 39 carried by I the lever 32 cooperates. v

j A. spring 40 is attached to the bracket l'? and the collar 28, and operates to hold the standard 18 y.':eldably in its lower position,

while a like spring 41 is coupled to the bracket 19 and the collar 29, and operates to hold the standard 20 yieldable in its lower position. I

By this arangement the standards 18 and 20 together with the guide wheels 22 and 23 may be adjusted vertically, and retained in adjusted position, and the vertical position changed as required by adjusting the stop collars 24 and 26.

Attached tovthe frame member 11 is a guide hanger 42 for a standard 43.- the latter vertically and rotatively adjustable in the hanger and held in adjusted position by a set screw 44. p

The standard 43 is formed with a laterally and downwardly directed offset 45, and

rigidly coupled at 46 to the lower end of the offset is an arm 47, with the outer portion divided to receive, a plate member 48. the latter pivoted at 49 between the free ends of the divided portion of the standard. 7 "The plate member 48 increases in width toward the free end, and is formed with a plurality of spaced apertures 49 to receive a holding bolt 50 extending through the sides of the divided portion of the standard. V

At the end opposite to the perforated enlargement the plate member 48 is enlarged vertically as at 51, the latter portion perforated to receive the-journal 52 of a disk member 53. j

By this means the disk may be adjusted to any required extent within the range of the apertures 49 of the plate 48, to adjustably control the angular action, and the standard 4445 also adjusted to control the lateral position of the disk. V j I Pivoted at 54 to the rear end of the frame member. 11 is a beam 55. j V

Attached to the team 55 intermediate the ends is 81. ts receive a standard 62;

the latter having a laterally direel'ed journal or at the lower end to Hll QpUll a re: 1 guide wheel til.

The three guide wheels L --22) and 61 are provided resperlively with annular guide ribs to prevent lateral disphieenlent while moving over the ground.

illounled on the standard (32 near the up per end are spared, slop eoliars U5 adjuslably roupled to the standard by set screws (36.

An adjusting collar 7 loosely engages the standard (l2 between the stop collars the A lever ti is pivoted at (lit to the hang i (ii and eonpled h a link ill to the rollar (1T.

lhe hanger til is prorided with a toothed segment Tl with whieh a pawl deviee 'i'Ll arried by the lever tin rooperales. It spring; T l is attaehed to the hanger til and to the collar (li'. un o erates to hold the standard til. yieldably in its lower position. li y th s; arrau nunent the standard re together with the jIllltlO wheel (ll may he adju-ted veriraliv and retained in adjusted position. and the vertical position ol' the standard rhanggieih as required by adjusting the stop eollars l'ii.

li i iOtl at 56 to the tear end of the trains? member 10 is a brace set-lion 5i. and pivoted at ill to the beam 35, is a brave seetion 59, the brace seetions ove lappine' and each provided with a plurality of transverse apertures to receive holding bolts to enable the brace sections to be adjusted to control the :n'igular position of the beam relative to the supporting:- frame.

"The hanger (ll ineludes a evlindrieal body which. enaagres in a semi-(tire: lar seat in the outer tare ol the beam and an ext in seat for the hanger shown at Tl. to allow the lnuurer to be disposed rearwardly of the position in higlures l and 2h wbieh will he required when the angularity ol: the beam eliaiured through the eoaetion ol the brare oer-lions :"ii' and 59.

l orn'ie ,l in the outer 'laee ot the beam at uni'lorinlv spaced intervals are suits To like the suit T-l, to alternately rereive banners to. eaeh oi the latter to receive a standard member 77.

lllounl'ed on aeh of the standards above and below aeh ol" the hane'eri-i. are atop eollars T8. adjnslahly coupled to the nlainilard h v set screws llv this means the standards T7 are tree to rotate in the hangers Th. but ar: adjustablv supported vertieall v therein.

.llirfidlv roupled at t ll to eaeh ot the standdars at the lower end is a divided arm, a portion o'l. whieh is represented at 81. the latter being identieal with the arm 47 shown in l ie'nres 3 and 4;. and each supportinn' a cutting; disk 82.

The cutting disks employed in this Inaehine are dish shaped or eoneavo-eonvex and these disks are eXtren'iely shallow as shown in the sectional view Figure i. A disk. of :21) or 2; inehes diameter should have a dish oi l'rom one-hall to three-1pmrters of an inrh, which nrakes it easy to use giving an easy running iuaehine.

Near its upper end earh ol the slaudarnr-i is provided with a turning: arui till and eaeh held adjnstahlv upon the standard by a ret. serew t l ll their outer e ids the turning: arms ll?) are eoupled to an :nljustinr; roi whereby the standards Ti may be siiunil ineousl v rotated to eontrol the angular posi tion of the disks.

lllounted on the beam of ii: whieh a lever H5 is pivoted a eouphJ'd at lit) to the rod r 5.

Formed upon the ljn'aeltet tilt is a toothed segment .lll with whirh a pawl Ell rarried by the lever on (titll'ltlilltrfl to hold the lever in adjusted position.

By this means the standards and the disks earried thereby may be, simultaneously rotated and retained in adjusted position.

The trains lllt lltl -"lh' l2 and H are provided with a plurality of spaced apertures to adjnstahly support a, draft bar 92, as shown.

A spring )2 is eonneeted between a hraeket 93 and the rod 85, to vieldablv hold the standards.

The improved device may be constructed o1 any suitable material and ot any required size and to contain any required number of the disks.
